`Z, T` for setting the cell at the top?

[llinfeng]

Similar to how Z, Z centers the cell, how to make Z, T available for setting the current cell to the top of the "view"? I found it in the vim-plugin for Jupyter notebooks and have been longing for it in JupyterLab.

Apologize for the wild and lazy ask :)

And, many thanks!

If this gets implemented there should be an equivalent Z, B for moving it to the bottom.

This will require adding a new command similar to https://github.com/axelfahy/jupyterlab-vim/blob/bbb7569c465e3b635f08fb4df12e05de350364dc/src/index.ts#L429-L440
